STAMPING-MACHINE.

EPECIFICATION forming part of Letters Patent No. 658,672, datedSeptember 25, 1900.

Application filed January 30, 1900. Seria1No.3,358- (No model.)

To (11M Lu/tom, it Duty concern:

Be it known that I, CHARLES M. PIERCE, a citizen of the United States,residing at WVeston, in the county of Umatilla and State of Oregon, haveinvented a new and useful Stamping-Machine, of which the following is aspeciiication.

The invention relates to improvements in stamping-machines.

The object of the present invention is to improve the construction ofstamping-machines and to provide a simple, inexpensive, and efficientone designed for use in banks, railroad-offices, post-offices, and thelike, and capable of being rapidly operated by either the foot or handand of automaticallyinking itself after each operation.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereunto appended.

In the drawings, Figure 1 is a perspective View of a stamping-machineconstructed in accordance with this invention and arranged to beoperated solely by hand, the stamp being in engagement with the table.Fig. 2 is a side elevation showing the stamping-machine constructed tobe operated either by hand or foot, the stamp being in engagement withthe ink-pad.

Like numerals of reference designate corres pending parts in bothfigures of the drawings.

1 designates a base, from the rear portion of which rises a shortupright or post 2, having its upper end bifurcated and receiving theangle of a bell-crank lever 3, which is fulcrumed on a pivot 4. Thebell-crank lever is provided with a short rearwardly-extending arm 5,which is connected with a coiled spring 6, and it has a longupwardly-extending arm 7, which is connected with alongitudinally-movable bar 8, that carries a stamp 9. The coiled spring6 is secured at its lower end to the base, and it is adapted to bedistended, as illustrated in Fig. 1 of the accompanying drawings, whenthe stamping-inachine is operated and when the stamp is in engagementwith a table 10, whereby the stamp will be returned to its normalposition when the operating mechanism is released. The upper end of thearm 7 of the bell-crank the links 12 are connected with the upper end ofthe standard, the width of which is reduced by means of a transversebolt 14 or other suitable pivot, and the upper ends of the links arepivoted to opposite sides of the bar 8 by a pin 15 or other suitablepivot. When the device is operated, the links oscillate from theposition shown in Fig. 2 to that illustrated in Fig. l, and the spring 6serves to return the links after the device has been operated by themeans hereinafter described.

The stamp preferably consists of a head provided at its lower face withsuitable characters and having an extension 16, arranged between twoparallel members 17 of an adjustable clamp, which is mounted on thelaterallyextending arms or portions of the T-shaped bar 8. The membersof the clamp consist of short plates or pieces bolted or otherwisesecured to the opposite faces of the extension 16 of the stamp andprovided at their rear ends with openings 18, through which thelaterally-extending arms of the bar 8 pass. The members are provided atthe top walls of the openings with threaded perforations for thereception of set-screws 19, whereby the members are secured at thedesired adjustment, the screws being adapted to engage the saidlaterally-extendin g arms. The plates or members, which are perforatedfor the reception of suitable fastening devices for securing them to thestamp, may be fastened to the ends of the stamp and stamps of any sizemay be applied to the members of the clamp; also, the members arecapable of adjustment to position the stamp over difierent portions ofan inkpad 20.

The ink-pad 20, which may be of any desired constrnction,is located inrearofa table 10 and may be supported by an extension thereof, asillustrated in the accompanying drawings,

The table,which is shown in the accompany ingdrawingsasataperingortriangular block, is provided at its upper face with acushion 22, of felt or other suitable material, to avoid injuring thetype of the stamp. The inner end or apex of the block is cut away orrecessed at the top to form the shelf 21, which is inclined,asillustrated in the accompanying drawings.

The bellcrank lever is oscillated by an operatinglever 23, looselyfulcrumed in a slot or bifurcation of a post 24 and having its rearportion bent inward at right angles and provided with a perforated earwhich is pivoted to the short arm of the bell-crank lever. The frontpurl ion of the lever is extended outward laterally at 25 and isprovided with an approximately L-shaped handle portion 26, extendingforward and arranged within con venient reach and adapted to bedepressed to operate the stamping-machine. As soon as the o.)erating-lever is released the spring will return the parts to theirnormal position. A treadie 27 may be connected by a rod 2a with theoperating-lever to enable the device to be operated by foot-power, andwhen the treadle is employed the rod is preferably extended through thebase, as indicated in Fig. 2 of the drawings. By loosely fulcruming theoperating-lever in the bifurcation of the post 24 it is permitted thelimited longitudinal movement incident to the oscillation of the shortarm of the bell-crank lever.

It will be seen that the stamping-machine is exceedingly simple andinexpensive in construction, that it is adapted to be quickly operated,and that it may be employed advantageously in banks, post-otfices, andrailroadoifices and analogous places where a large amount of stamping ina comparatively short time is necessary.

Changes in the form, proportion, size, and the minor details ofconstruction within the scope of the appended claims may be resorted towithout departing from the spirit or sacrificing any of the advantagesof this invention.

What is claimed is 1. In a machine of the class described, thecombination of a support, a longitudinallymovable bar connected with thesupport and provided at its front end with laterally-disposed arms,mechanism connected with the longitudinally-movable bar for actuatingthe same, the forwardly-extending clamp members having openings toreceive the laterallyextending arms and provided-with means for engagingthe same, whereby the clamp members are adapted to be adjusted towardand from each other, and a stamp secured between the clamp members andlocated in advance of the longitudinally-movable bar, substantially asdescribed.

2. In a machine of the class described, the combination of a base havinga fixed support to receive the work, a standard, alongitudinally-movable bar extending in advance and in rear of thestandard and connected at a point between its ends with the standard bya link, a stam p located in advance of the standard and connected withthe front end of the longitudinally-movahle bar, the bellcrank leverfulcrumed at its angle in rear of the standard and having its front armelongated and connected with the rear end of the longitudinally-movablebar, and a lever arranged approXimat-ely parallel with thelongitudinally movable bar and loosely fulcrumed between its ends andhaving its rear end bent laterally and pivoted to the rear arm of thebell-crank lever, and a spring connected with the latter, substantiallyas described.

3. In a machine of the class described, the combination of a base, afixed block mounted on the front portion of the base and adapted toreceive the work, a standard rising from the base in rear of the block,a longitudinallymovable bar extending in advance and in rear of thestandard and connected at a point between its ends with the standard bya link, a bell-crank lever fulcru med at its angle in rear of thelongitudinally-movable bar and having one of its arms elongated andpivoted to the said bar, a post having a slot or bifurcation, and anoperating-lever loosely fulcrumed in the slot or bifurcation andextending longitudinally of the machine and having its rear end bent atan angle and pivoted to the bellcrank lever, substantially as described.

In testimony that I claim the foregoing as my own I have hereto afiixedmy signature in the presence of two witnesses.

CHARLES M. PIERCE.
